Unveiled on Monday by the USB Implementers Forum, the USB 3.0 spec can theoretically support data-transfer speeds of up to 4.8Gbps - 10 times the speed provided by USB 2.0. The new standard, also known as SuperSpeed USB, is also expected to be more power-efficient than its predecessor. "SuperSpeed USB is the next advancement in ubiquitous technology," Jeff Ravencraft, the president of the USB Implementers Forum (USB-IF), the industry group that promotes USB technology, said in a statement on Monday. "Today's consumers are using rich media and large digital files that need to be easily and quickly transferred from PCs to devices and vice versa. SuperSpeed USB meets the needs of everyone, from the tech-savvy executive to the average home user."
